This study examines the importance of Myanmar for the formation of a Sino-centric macro-region through the Belt and Road Initiative (BRI). The authors rely on the transit of power theory that helps to analyze systemic imperatives and internal characteristics of China’s foreign policy. The authors applied the principles of historicism, scientific objectivity and reliability. In the first part of the work, the Chinese Belt and Road initiative is studied as a geostrategic tool of the People’s Republic of China (PRC). The authors consider the features of its development and the strategic results of its implementation. In particular, the article emphasizes that this initiative is aimed at the formation of a Sino-centric macro-regional space. Based on this, the role of Myanmar is characterized as essential. The geographical location of this state allows China to gain access to the Indian Ocean, a transit region for energy resources, as well as to overcome one of the strategic vulnerabilities of its geopolitical position - the ‘Malacca dilemma.’ Moreover, as a border state, Myanmar is an indispensable link in the implementation of land and gas energy transport corridors of macro-regional importance. Finally, in the context of strategic competition between the United States and China, the importance of ensuring stability in critical proximity to the PRC’s state borders is growing, especially in the absence of a stable internal state situation in Myanmar. Among the additional factors, the authors highlight the importance of the mood of state and local elites for the development of this initiative. In this regard, the analysis of China’s reaction to the military coup in Myanmar in February 2021 was particularly indicative that Myanmar is of key importance because of its strategic location between China and the Indian Ocean, as well as its resource potential.
